4.1.3 String functions</a>
</h2>

<p>
The following functions are available to operate on string and Unicode
objects.  They are not available as string methods.

<p>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-358' xml:id='l2h-358' class="function">capwords</tt></b>(</nobr></td>
  <td><var>s</var>)</td></tr></table></dt>
<dd>
  Split the argument into words using <tt class="function">split()</tt>, capitalize
  each word using <tt class="function">capitalize()</tt>, and join the capitalized
  words using <tt class="function">join()</tt>.  Note that this replaces runs of
  whitespace characters by a single space, and removes leading and
  trailing whitespace.
</dl>

<p>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-359' xml:id='l2h-359' class="function">maketrans</tt></b>(</nobr></td>
  <td><var>from, to</var>)</td></tr></table></dt>
<dd>
  Return a translation table suitable for passing to
  <tt class="function">translate()</tt>, that will map
  each character in <var>from</var> into the character at the same position
  in <var>to</var>; <var>from</var> and <var>to</var> must have the same length.

<p>
<span class="warning"><b class="label">Warning:</b>
Don't use strings derived from <tt class="constant">lowercase</tt>
  and <tt class="constant">uppercase</tt> as arguments; in some locales, these don't have
  the same length.  For case conversions, always use
  <tt class="function">lower()</tt> and <tt class="function">upper()</tt>.</span>
